OpenWRT

[1001crew]

I'm trying to figure out why all the mesh agents build for linux are not working in their correspondent same architecture version of Open WRT. One example is : Raspberry PI 3 (cortex_a53) If I use Raspbian or Dietpi linux, mesh agent work smoothly If I use OpenWRT (for Raspberry pi3), mesh agent return me the following error: './meshagent: line 1: syntax error: unexpected word (expecting ")")'

We have no clue on that, except that probably OpenWRT for Rpi3 has kernel build without Hard FP.

Is there anybody that experienced the same problem ? This type of problem we are facing with any ARM board and with majority of routers using OpenWRT based on ARM chipset.

Which agent are you using?

[krayon007]

Most standard linux builds will not work on openwrt, because openwrt does not use glibc. It typically uses musl or uclibc. In order to work on openwrt, you need to use a cross compiler for whatever openwrt version you are using.

I used a cross compiler for openwrt v18 on MIPS24Kc, for agent 28

25 : Linux ARM - Hard Float

It's not working neither with RASPBERRY PI (openWRT), nor FRIENDLYARM NANOPI ZERO (FriendlyWT) and also not with FRIENDLYARM NANOPI R1 (OpenWRT). All three have the same CPU. All three board are okay with meshagent #25 if used with RASPBIAN (RPI3B), DIETPI (NANOPI)

Okay thanks for clarification. I have forwarded your reply to OpenWRT developer in charge of this. Let's see his comments.

In case of chipset MediaTek MT7620A or MediaTek MT7621A is there a way to have meshagent work/compiled for OpenWRT ?

The current MIPS24KC meshagent build doesn't work? I built the OpenWRT toolchain for that using ATH79 as the target. The only MediaTek target I see in the OpenWRT build config tools, is MediaTek Ralink MIPS. What version of OpenWRT did you say are running? The toolchain I built is based on Openwrt v18.06.1

The current MIPS24KC meshagent build doesn't work? NOPE, sadly! I tried to upload all versions linux 32bit...

And this is for chipset mediatek7621 https://downloads.openwrt.org/releases/19.07.5/targets/ramips/mt7621/ https://downloads.openwrt.org/releases/19.07.5/targets/ramips/mt7621/config.buildinfo

I'm building the toolchain for MT7620 right now... I'll post back with a meshagent for you to test, when I get it compiled with this toolchain.

[krayon007]

Ok, try this agent. Unzip this file, and run the command to see if it works: ./meshagent_mipsel24kc -info

From what I found, it looks like the Atheros build target I used for OpenWRT mips24kc is big endian, but the MediaTek one is little endian. (Or vice versa, I can't remember what the description said) So I built a new toolchain for MediaTek 7620, and used it to build the agent below.

BINGO !!!!!!

Working perfectly !!!

[1001crew]

Thank you so much !!!!!

I will try this with other MT7620 chipset router....

Great Job. My infinite Thanks once again...

I would suggest you to add this agent in the '/meshagent' list of those downloadable

[1001crew]

Too rush... Is it normal that TERMINAL tab is missing ??? And also info about agents, and other details are missing...

This is another SBC (NANOPI ZERO which run Raspberry Pi agent):

[krayon007]

This would be a good @Ylianst question. There should be a file and terminal tab. I assume all your other agents connecting to your server have these tabs?

[1001crew]

Yes indeed. All connected agents have both terminal and files except this OpenWrt

How do we build if the target arch is not within makefile.

I am trying to build for Orange Pi R1 Openwrt openwrt-toolchain-sunxi-cortexa7_gcc-7.3.0_musl_eabi, I have the toolchain already. Any help if much appreciated.

[krayon007]

The first step is to compile openssl using the tool chain. Then you'll need to copy the two .a files into the libstatic folder, then modify the makefile.

If you post the tool chain somewhere, or show me where to get it, I can make the changes for you.

Hello @krayon007 ,

This is the link for the toolchain https://github.com/r1bnc/openwrt18-orangepi-r1-toolchain-sunxi-cortexa7_gcc-7.3.0_musl_eabi

Hello @krayon007, any update?
